Neon C3298DVB - odd picture

(1/4) > >>

Turnip:
Hi folks,

Have one of these 'Morrison's' specials with a dark picture with flickering vertical bands mainly at the centre. Power board is AYP41801, Main CV109H and inverter CMO I315B1-16A. Screen a Chi Mei V315B1-L01.

Any thoughts on this one ?  - Chris

hi chris
the eeproms are a stock fault on these sets, mainly causing stuck in standby faults, but yours sounds like a screen problem, have you attached the scart to another set to check pic?
i have one of these sets myself which is stuck in standby, another engineer has buggered about with it, he changed the fault from no freeview to stuck in standby, suspect corrupt eeprom, reluctant to buy eeprom incase he has caused more damage. perapse if mine uses the same screen (will check in the morning) you could send me your av and tcon pcb and i will check them on my screen and at the same time i will check your eeprom in my set to see if that is all that is wrong with it?
hopefully confirming the faults on both tvs
just a thought.

just checked, wrong screen, typical!!!!
would still be interested to try the eeprom if you decide the screen is the fault
thanks

Hi Daz and thanks,

Scart out pic is fine - took a pic with Scart in from a digibox as own pic too dark to see - looks like LDVS to me - anyone got a V315B1-C01  ?

Thanks again - If I land the set will send EEprom - Chris

hi chris
check the regs are kicking out the correct voltage , had a run of v320b1-c03 tcon pcbs which look identical to yours, give all sorts of graphics problems, due to low voltages out of the regs. you should have a 2.5v and a 3.3v reg on the pcb,
good luck
